An intoxicated driver fleeing police plowed his car into a crowd at the South by Southwest festival in Austin, Texas, early Thursday, killing two people, authorities said.

The driver, who now faces two counts of capital murder, Texas' highest offense, hit pedestrians, a moped, a taxi, a bicycle and a van, said Austin Police Chief Art Acevedo. Authorities will not release the driver's identity until he is formally charged.

The suspect also faces 23 counts of aggravated assault by vehicle, Acevedo said.

Police have not identified the dead, but they were a Dutch man on a bicycle and a local woman on a moped, Acevedo said, correcting his earlier statement that the victims had been on a motorcycle.

MassiveMusic, a music agency with offices around the world, posted a statement on its website and Facebook page identifying the company's Amsterdam-based creative director, Steven Craenmehr, as a person killed Thursday in Austin.

'During the 8 years that Steven worked for MassiveMusic, we got to know him as an unstoppable force, full of life, love and laughter,' the Facebook post said. 'This is an irreplaceable loss for the MassiveMusic family, and we are grateful for the years we spent with him. Our thoughts are with Steven's family and friends.'

Twenty-three others were hospitalized, some with multiple internal injuries. Most of the victims were in their 20.
